SPECIFICATION forming part ofLetters Patent No.349f742, dated September28, 1886.

' Application filed April 19, ices. Serial No. 199,401. (No loam novelconstruction and combination of parts,

substantially as hereinafter fully set forth,-and

specifically pointed out in the claim.

The object of my invention is to overcome of geared windmills which areliable to be thro wn out of the wind when the vertical shaft thereofencounters resistance and strain in setting the machinery in motion thatit is designed to drive; and, further, to simplify the construction ofthe mill and thus also cheapen or lessen the cost of the manufacturewhile at the same time the parts shall be strong and durable andeffective in operation.

In the accompanying drawings, Figure l is a front elevation of awindmill embodying my invention, the tower and arms of the wheel beingpartly broken away. Fig. 2 is a top plan view thereof. Fig. 3 isa sideelevation of my improved mill.

Referring to the drawings, in which like figures of reference denotecorresponding parts in all the figures, 1 designates the tower of thewindmill, a portion only of which is shown, and which is of the ordinaryor any preferred construction; and 2 the turn-table that is rotativelymounted or journaledon the tower to adapt it to revolve with the wheeland other devices or mechanisms which it carries. The

table extends down into the tower, and it,

bears on a bridge-tree, 8, at its lower end, and

.by which it is supported, and this bridge-tree p The lower end of theturntable bears on the bridge-tree around the opening 6 therein and thecap-plate 8 bears against the lower face of the bridge-tree, to preventthe turn-table from being elevated out of and carried awayfrom the towerby the high winds, the straps or bolts 7 and cap-plate-S being carriedby the turn-table in its movements. The upper end of the turn-table isprovided with an outwardly-flared circumferential edge, -10,wl1ich bearsin the curved inner edge of a socket-plate, 9, that is bolted directlyto and supported by the windmill-tower 1.

l1 designates the wind-wheel, which is arranged to one side of the towerand the turntable thereon, and the wheel is of any preferredconstruction. The wheel is provided with a central hub, 12, that isrigidlysecured or keyed on a shaft, 13, a series of radial arms, 14, anda ring or annulus, 15. The inner ends of the arms are secured in thehub, and they I may be braced and strengthened in any preferred manner,and carry blades of suitable construction. The ring or annulus isarranged concentric with the hub, and is of considerably larger size,and at its pheriphery it is provided with a series ofperf0ratedlugs,16,which bear against the radial arms, and are securedthereto to brace and strengthen the same by through-bolts 17 while onthe inner edge the and journaled in bearings 19, that are supported bystandards 20, which are secured to the turn-table and carried thereby.Suitable collars are secured on the wind-wheel and counter-shafts toprevent longitudinal play thereof in their respective bearings, or otherequivalent devices may be employed for effecting the same result;' andat one end the counter-shaft is {provided with a pinion, 21,

that meshes with and is rotatedv by the circular rack 15 of thewind-wheel 11, the pinion being arranged within and eccentric with theperiphery of the said ring or rack. At its middle, or thereabout, thecounter-shaft carries abevel gear-wheel, 22, that is rigidly secured orkeyed thereon, and the bevel gearwheel meshes with and rotatesasmallerbevelpinion, 23, that is arranged to rotatein-a plane at rightangles to the plane of the wheel 22. The bevel-pinion is rigidly securedon a vertically-disposed shaft, 24, that extends through the tower andthe turn-table thereof, and the said pinion 23 is secured on thevertical shaft above a bridge-tree, 25, which is arranged across thecentral opening in the turn-table, and is bolted at its ends to theturn-table, and is carried thereby in its rotatory movements. Thebridgetree supports the vertical shaft at its upper end, and the shaftis used to drive the machinery of any class, and the turn-table rotatesaround the vertical shaft without affecting the latter. The vane or tail26 is rigidly secured to the turn-table by bolts or otherwise, and thevane is arranged on the oppo-- site side of the tower to the wind-wheel.The vane 'is arranged on the opposite side of the counter-shaft to thewheel-shaft, and it is inclined to the said counter and wheel shafts ordisposed diagonally with relation thereto, as

clearly shown in the plan View, Fig. 2, of the.

drawings. By thus arranging the wind-wheel shaft out of the usual lineof the turntable, I utilize the force of the wind thereon tocounterbalance or equalize the strain on-the vertical shaft that iscaused and due to the resistit the circular rack, which drives with itthe pinion and the counter-shaft, and th bevel gear-wheel of the lattershaft rotates the bevelpinion and the vertical shaft that drives theWhen the wheel rotates, it carries with machinery, and when thewindshifts or changes the vane turns the wheel to keep it in the wind, andthe turn-table also rotates with the wheel and carries with it thevarious shafts and j ournal-bearings. v.

The operation of my invention will be readily understood from theforegoing description taken in connection with the drawings.

I do not confine myself to the exact details of construction and formand proportion of parts herein shown and described as an embodiment ofmyinvention, as I am aware that changes therein can be made withoutsacrificing the advantages of my invention.

I attach especial importance to the shaft journaled on a turn-table andarranged to one side of the axial line thereof, and carrying a wheel anda rack, a counter-shaft also journaled 011 the turn-table parallel withthe wheelshaft and having a pinion meshing with the rack, and aregulating-vane also carried by the turn-table and arranged at an angleto the wheel and counter shafts, and on the opposite side of thecounter-shaft to the wheel-shaft, as therein lies the gist of myinvention, whereby the resistance and strain on the parts expe riencedin setting the machinery in motion which the wheel is designed tooperate, is entirely overcome.

Having thus fully described my invention, What I claim as new, anddesire to secure by 'Letters Patent,.is'

to the table diagonally to the wheel and counter-shafts, and on theopposite side of the countershaft, substantially as described. I

In testimony that I claim the foregoing as my own I' have hereto affixedmy signature in presence of two witnesses.
